How to use this page well
These pages work best when they behave like tools, not essays. Use the quick structure first, then apply it to the exact journal and manuscript situation.
Question | What to do |
|---|---|
Use this page for | Getting the structure, tone, and decision logic right before you send anything out. |
Most important move | Make the reviewer-facing or editor-facing ask obvious early rather than burying it in prose. |
Common mistake | Turning a practical page into a long explanation instead of a working template or checklist. |
Next step | Use the page as a tool, then adjust it to the exact manuscript and journal situation. |
Quick answer: a strong Nano Letters cover letter proves a single clear physical insight at the nanoscale. It should explain what was learned about how a nanoscale system works, not just demonstrate good characterization.
What Nano Letters Editors Screen For
Criterion | What They Want | Common Mistake |
|---|---|---|
Physical insight | A single clear physical insight about a nanoscale system | Describing thorough characterization without stating what was learned |
Nanoscale focus | Insight depends on the nanoscale nature of the system | Reporting results that do not require nanoscale physics to explain |
Letter scope | A single focused result matching the short-format Letter style | Trying to fit a multi-part study into the short communication format |
Journal distinction | Clear reason for Nano Letters vs. ACS Nano (longer format) | Submitting work that needs extensive characterization data better suited for ACS Nano |
Conciseness | Cover letter matches the journal's concise communication ethos | Lengthy cover letters that do not match the Letter format culture |
What the official sources do and do not tell you
The official Nano Letters pages explain formatting requirements and the short-format style, but they do not prescribe one ideal cover-letter formula.
What the journal model does make clear is:
- the manuscript should offer genuine physical insight at the nanoscale
- the editor needs to see the insight quickly - this is a Letter, not a comprehensive study
- the letter should clarify why the work belongs in Nano Letters rather than in ACS Nano or a broader materials journal
That means the cover letter should not read like a characterization report with a physical-insight paragraph appended.
Use Nano Letters when your paper has a single striking nanoscale result that does not need extensive characterization to be convincing. Use ACS Nano when the full characterization story is the strength. A Nano Letters cover letter framing check is the fastest way to pressure-test whether your framing meets the editorial bar before submission.
What the editor is really screening for
At triage, the editor is usually asking:
- what is the nanoscale physical insight?
- does the paper explain why a nanoscale system behaves the way it does, or just measure that it does?
- is this a Nano Letters paper, or a better fit for ACS Nano, Advanced Materials, or a physics journal?
- does the result fit the short-format Letter scope?
Academic editors who are active nanoscience researchers make these triage decisions. They can spot a characterization paper disguised as an insight paper quickly.
What a strong Nano Letters cover letter should actually do
A strong letter usually does four things:
- states the physical insight at the nanoscale directly
- explains why this insight changes understanding, not just measurements
- shows why the short-format Letter is the right scope for this finding
- positions the work for the broad nanoscience readership
If the finding needs extensive characterization to land, ACS Nano may be the stronger venue.
A practical template you can adapt
Dear Editor,
We submit the manuscript "[TITLE]" for consideration at
Nano Letters.
This study reveals [nanoscale physical insight]. We show that
[main result], which changes how researchers should understand
[nanoscale phenomenon / mechanism / property].
The Letter format is appropriate because [the insight is sharp and
self-contained]. The result matters to readers interested in
[broader nanoscience audience], not just [narrow subfield].
This work is original, not under consideration elsewhere, and
approved by all authors.
Sincerely,
[Name]That is enough if the physical insight is real and sharp.
Mistakes that make these letters weak
The common failures are:
- leading with characterization data instead of the physical insight
- claiming novelty without explaining what was learned
- writing a letter that could describe an ACS Nano paper rather than a Letter
- using "for the first time" claims without making the insight clear
- burying the nanoscale advance behind synthesis or fabrication details
These mistakes tell the editor the paper is a characterization study, not an insight paper.

What Nano Letters specifically requires (from ACS author guidelines)
Unlike many journals that treat cover letters as optional formalities, Nano Letters has specific requirements:
1. Suggest 6-8 competent reviewers. This is not optional. ACS author guidelines state: "Authors are urged to suggest in the cover letter a minimum of six to eight persons competent to review the manuscript." Suggested reviewers must not be at the same institution as any author. This is a higher reviewer-suggestion requirement than most journals, Nature asks for recommendations but does not specify a minimum number.
2. Justify the need for rapid publication. The guidelines ask authors to "provide enough background to justify the need for rapid publication" of high-impact results. This phrasing tells you what the editors expect: the finding should be striking enough that a short-format Letter is the right vehicle, not a comprehensive study.
3. State goals and significance clearly. "A clear statement of the manuscript's goals and significance is very helpful for the Editors." This is different from restating the abstract, it's about explaining why the result matters and why it merits the Letter format.
4. Disclose preprint postings. If you've posted to arXiv, ChemRxiv, or another preprint server, state this in the cover letter with the relevant link and date, and explain how the manuscript has been adjusted between deposition and submission.
The four mistakes that kill Nano Letters cover letters
1. Describing characterization instead of insight. "We synthesized nanoparticles and characterized them by TEM, XRD, and UV-Vis" is a methods summary. "We discovered that quantum confinement in sub-3nm particles produces an anomalous Stokes shift that cannot be explained by current theoretical models" is a physical insight. Nano Letters wants the second version.
2. Overselling without a clear physical mechanism. "First-ever" and "record-breaking" claims do not help unless the cover letter also explains why the result occurred. A record property without a mechanistic explanation belongs at a materials journal, not at Nano Letters.
3. Submitting a multi-part study in Letter format. If the cover letter describes three experiments that each make a separate point, the paper is an ACS Nano article, not a Nano Letters Letter. The cover letter should describe one insight, not three findings.
4. Failing to suggest 6-8 reviewers. This is an explicit ACS requirement. Omitting reviewer suggestions signals unfamiliarity with the submission process and does not help editors, who are active nanoscience researchers juggling review duties alongside their own research.
Nano Letters vs ACS Nano: what the cover letter should distinguish
Both are ACS journals in nanoscience, but the cover letter must signal which format fits:
Factor | Nano Letters | ACS Nano |
|---|---|---|
Format | Short Letters (under 3,000 words, max 5 figures) | Full articles (no length limit) |
Editorial expectation | One striking insight, concisely presented | Comprehensive characterization + application |
Cover letter length | Match the Letter ethos, concise | Can be longer if the story is complex |
Reviewer suggestions | 6-8 minimum | Standard ACS requirements |
If your cover letter needs to explain multiple experiments in detail to make the case, your paper may belong at ACS Nano, not Nano Letters. The cover letter should be as concise as the paper itself.
Publication costs
Venue | Model | Typical cost |
|---|---|---|
Nano Letters (subscription) | No page or color charges | $0 to authors |
Nano Letters (gold OA option) | ACS AuthorChoice | ~$3,000-$4,000 |
ACS Nano (subscription) | No page or color charges | $0 |
Small (Wiley, OA option) | Hybrid OA | ~$5,510 |
Nano Letters does not charge page or color charges for subscription publication. ACS AuthorChoice pricing for gold OA is lower than Wiley's hybrid OA for comparable journals.

Frequently asked questions
It should state the nanoscale physical insight directly and explain why the result changes understanding rather than just demonstrating good characterization.
A common mistake is describing thorough characterization data without explaining the physical insight. Editors want to know what was learned, not just what was measured.
Nano Letters publishes short-format papers emphasizing a single clear physical insight. ACS Nano accepts longer papers with broader scope and more extensive characterization. If your story needs many figures and supplementary data to work, ACS Nano is the better fit.
No. The journal uses a short-format Letter style, and editors expect the cover letter to match that conciseness.
